Positioning winform to the center screen does not work

I have an issue regarding the location of the window in my Winforms application.

I need to position the window in the center of the screen during start up. I tried the following but that didn't work. The form always opens at the top left corner.

I tried these in the load event:

this.CenterToScreen();
this.Location = new Point((Screen.PrimaryScreen.WorkingArea.Width - this.Width) / 2,
                          (Screen.PrimaryScreen.WorkingArea.Height - this.Height) / 2);

Update: i have given the form maximum and minimum size as 1090,726.

my designer file has this code:

        this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
        this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
        this.BackColor = System.Drawing.SystemColors.GrayText;
        this.ClientSize = new System.Drawing.Size(1074, 688);
        this.Font = new System.Drawing.Font("Microsoft Sans Serif", 8.25F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
        this.Icon = ((System.Drawing.Icon)(resources.GetObject("$this.Icon")));
        this.Margin = new System.Windows.Forms.Padding(3, 4, 3, 4);
        this.MaximizeBox = false;
        this.MaximumSize = new System.Drawing.Size(1090, 726);
        this.MinimumSize = new System.Drawing.Size(1090, 726);
        this.Name = "Mail_Remainder";
        this.RightToLeftLayout = true;
        this.SizeGripStyle = System.Windows.Forms.SizeGripStyle.Hide;
        this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;
        this.Text = "Remainder";
        this.WindowState = System.Windows.Forms.FormWindowState.Maximized;
        this.Load += new System.EventHandler(this.Mail_Remainder_Load);
        this.Resize += new System.EventHandler(this.Mail_Remainder_Resize);
        this.ResumeLayout(false);
        this.PerformLayout();

Any other way to do this?

Please help.

I had a similar problem; after CenterToScreen () the form was off-center. Then I noticed I was doing this BEFORE InitializeComponent (). I moved it after InitializeComponent and it worked fine.

Give a look at the following: 

 Form1.StartPosition = FormStartPosition.CenterScreen;
 Form1.Show();

Edit:

The line 

 this.WindowState = System.Windows.Forms.FormWindowState.Maximized;

is the one causing the decentering.

If you comment it:

    private void InitializeComponent()
    {
        this.SuspendLayout();
        // 
        // Form1
        // 
                    this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
        this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
        this.BackColor = System.Drawing.SystemColors.GrayText;
        this.ClientSize = new System.Drawing.Size(1074, 688);
        this.Font = new System.Drawing.Font("Microsoft Sans Serif", 8.25F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
        this.Icon = ((System.Drawing.Icon)(resources.GetObject("$this.Icon")));
        this.Margin = new System.Windows.Forms.Padding(3, 4, 3, 4);
        this.MaximizeBox = false;
        this.MaximumSize = new System.Drawing.Size(1090, 726);
        this.MinimumSize = new System.Drawing.Size(1090, 726);
        this.Name = "Mail_Remainder";
        this.RightToLeftLayout = true;
        this.SizeGripStyle = System.Windows.Forms.SizeGripStyle.Hide;
        this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;
        this.Text = "Remainder";
//            this.WindowState = System.Windows.Forms.FormWindowState.Maximized;
        this.Load += new System.EventHandler(this.Mail_Remainder_Load);
        this.Resize += new System.EventHandler(this.Mail_Remainder_Resize);
        this.ResumeLayout(false);
        this.PerformLayout();

    }

the window appears on the center of the screen.

Just set the StartPosition property of your form to be CenterScreen .....
